Description

[Detailed Description of the Invention] <Industrial Application Field> The present application relates to an improvement of a return lever attachment device in a coin sorting device used in a vending machine, a money changer, or the like.

<Prior art> Conventionally, a support plate is attached to the inner surface of the upper half of the substrate so as to be openable and closable, and the support plate is pressed by a spring and forms a gap between the inner surface of the substrate and the inner surface of the substrate to allow the passage of curing.
This support plate is opened and covered by operating a return lever, and a rotary plate interlocked with the return lever is rotated along the inner surface of the board, and the sorting plate is rotatably attached to the support plate. Hardening sorting devices are known which are configured to remove counterfeit coins that are attracted to a magnet.

That is, to explain this with reference to FIGS. 1 to 4 below, the substrate 2 is pressed by a spring 3 onto the inner surface of the upper half of a rectangular substrate 2, which has side pieces 1 bent inward on both side edges. One side of the support plate 4 is attached to the inner surface of the substrate 2 so as to be openable and closable via a shaft 5, forming a space between the support plate 4 and the inner surface of the base plate 2 to accommodate hardened currency. A passage member 6 is installed for guiding coins to the cash box and other coins or counterfeit coins to the return section. The support plate 4 has a cradle 7 for sorting predetermined coins.
The spring 3 and the shaft 5 are connected to each other by a member 10 having a limit lever 8 rotatably and a magnet 9 for attracting counterfeit coins to prevent them from passing and applying magnetic braking to passing coins. They are each rotatably attached to the support plate 4 via the support plate 4.

In addition to the adjustment attachment piece 11 on the outer surface of the board 2, the return lever 1 has a stopper piece 13 extending horizontally at the top and engaging with an arcuate hole 12 at the tip.
The base end of 4 is pivotally attached to the shaft 15.

This return lever 14 has a restoring spring 16
It is always held in a horizontal state, and when it is externally operated via the return button, it is rotated downward against the spring 16. The central part of the return lever 14 is connected to the board 2 through a hole 17 provided in the board 2.
A protruding shaft 19 is provided which protrudes from the inner surface of the support plate 4 and whose end surface comes into contact with a downwardly inclined slanted piece 18 provided by cutting and raising the support plate 4.
A rotary plate 20 is pivotally attached to the inner surface of the substrate 2 via a shaft 21, and rotates along the inner surface of the substrate 2 when the rotation plate 9 is lowered. 22 is a coin slot.

When the return lever 14 is rotated, the protruding shaft 19 descends as the return lever 14 rotates, and its end surface presses the inclined piece 18 and rotates in the direction of opening the support piece 4. The coins staying between the substrate 2 and the support plate 4 then fall and are returned.

Further, as the protruding shaft 19 moves, the rotary plate 20 rotates along the inner surface of the base plate 2, whereby the counterfeit coins attracted to the magnet 9 are also removed and returned.

<Problems to be solved by the invention> By the way, in the return lever 14 generally attached to this type of device, an operating piece 14' that is pressed in conjunction with the return button is bent at the upper edge of the lever 14. In the conventional case, the return lever 14 is arranged such that the operating piece 14' protrudes toward the outer surface of the board 2.
is attached to the base plate 2 by caulking the shaft 15 to enable the return lever 14 to swing relative to the base board 2, and the shaft 15 supports the winding portion of the restoring spring 16, and one end thereof is attached to the operating piece. On the underside of 14',
The other ends were respectively engaged with cut and raised pieces 23 provided on the substrate 2.

That is, according to the conventional structure, when attaching the return lever 14, the shaft 15 is first attached to the base plate 2, and then the base of the return lever 14 is caulked to the tip of the shaft 15, so that the return lever 14 can be freely rotated. Since it was installed, separate shaft mounting and caulking are required, and the installation work is troublesome and increases the cost.After the caulking process, the return lever 14 or the board 2 may be mechanically deformed or damaged. If a problem occurs and you want to replace them, you will have to break the caulking part and separate it.
Not only does it become impossible to reuse the shaft 15, it also damages the base of the return lever 14, and the separation process itself is troublesome.Therefore, in general, the return lever 14 is When a defect such as mechanical deformation occurs in the substrate 2, the uneconomical process of discarding the substrate has been taken.

<Means for Solving the Problems> Therefore, the purpose of the present application is to improve the defects of the above-mentioned conventional products, and the gist thereof is to A plate-shaped support piece is integrally protruded, and a hole bored at the base of the return lever is rotatably engaged with the support piece, and the winding portion of the restoration spring is fitted into the support piece. One end of the lever is locked to an action piece provided on the return lever, and the other end is locked to a locking piece provided on the base plate, and the tip of the folded piece is folded back to the restoring lever. The spring is characterized in that the coiled portion of the spring is held in place by being inserted into a hole provided in the support piece.

<Function> According to the present application, a plate-shaped supporting piece is integrally provided on a part of the base by cutting and raising it, and the base of the return lever is rotatably engaged with this supporting piece. Unlike in the past, there is no need to newly provide a protruding shaft on the board, and since the winding portion of the restoring spring is held down by the tip of the folded piece, there is no risk that the restoring spring will separate from the support piece. Furthermore, parts can be easily replaced by removing the tip of the folded piece of the restoring spring from the hole provided in the support piece.

<Embodiment> An embodiment of the present application will be described in detail below with reference to FIGS. 5 to 7. A plate-shaped support piece 30 is integrally provided on a part of the substrate 2 by cutting and raising it. A hole provided in the support piece 30 at the base of the return lever 14 preferably restricts rotation of the return lever 14 so that the return lever 14 is tilted downward at a required angle from a horizontal state with respect to the support piece 30. The restoring spring 16 is positioned inside the return lever 14 so that the end 16a abuts the action piece 14' and the winding part 16b is wound around the support piece 30. The other end 16c is fixed to a locking piece 32 provided on the base plate 2 and folded back, and the tip of the folded piece 16d is inserted into a hole 33 provided in the support piece 30 to attach the return lever. 14 from the support piece 30 is prevented by the other end 16c of the restoring spring 16.

In the above, the return lever 14 is rotated so that the hole 31 provided at the base of the return lever 14 is tilted downward at a required angle with respect to the support piece 30 from a substantially horizontal state. Since the hole has a restricting shape, when the return lever 14 is in a horizontal state, one edge of the hole 31 is aligned with the support piece 3.
When the return lever 14 is tilted at the required angle, the other end of the hole 31 comes into contact with the other side end of the support piece 30. , its tilted state is regulated, and therefore it is possible to omit the stopper that regulates the horizontal state and the tilted state of the return lever 14, respectively.

<Effect of the invention> Since the present application is constructed as described above, the restoring spring and return lever can be attached and removed from the board extremely easily, making it convenient for parts replacement and repair. In addition, it is economical because the return lever and board can be reused, and there is no need to newly install a protruding shaft to rotatably support the return lever, so it has the advantage of being inexpensive. have
